Good morning,
Do you mean the fuel pressure regulator or the pressure sensor for the fuel tank? there is no fuel pressure sensor for the fuel delivery system.
I attached a picture of the pressure sensor for the EVAP system for you to view.
What leads you to believe it has failed? This is not a common failure.

Do you have any codes?
